Benefits of technology

[0013]g. provides for an improvement over existing toy hoops and more particularly a hoop that is constructed of a lightweight semi flexible tubing material that provides suitable rigidity for effective twirling about ones body yet may be collapsed and deployed in a controlled, non- sudden fashion, for safe easy storage and transport.

Problems solved by technology

Hoops of this type are large and are not designed to be compactable for travel and storage (typically hoops of this type are 28-30 inches in diameter for use by children and 34-36 inches in diameter for larger individuals) and can be difficult to store and tote about when not in use so they are not convenient to bring along when one goes from place to place.
This type of hoop takes time to assemble and disassemble.
Prior art shows that the deployment of some types of pre-stressed hoops can be sudden and uncontrollable.

Embodiment Construction

[0021]Referring to FIGS. 1-6. Referring to FIG. 2 a pre-coiled linear length of plastic tubing is shown that may have an over-all length of approximately 96 inches. A 96 inch tube will form a hoop roughly 30 inches in diameter. FIG. 5 shows a tube mating union or coupling 12 that is designed to be forcibly inserted or threaded inside the ends of tube 20. That is to say that the outside diameter of the threading 34 is a larger diameter than the inside diameter of tube 20. The sharp metal threads of coupler 12 will cut into and seat in the softer plastic material of the tube 20 preventing the coupling from being pulled out after assembly yet allowing for rotation of the tube around the threaded metal coupling. Referring to FIG. 4. When tube 20 is manufactured as in an extrusion process the material, while still hot, can be formed into a continuous coil with an approximate diameter of 14 to 20 inches and allowed to cool in that condition. A collapsed hoop can then be assembled from thi...

Description

[0001]This Non-Provisional application is referenced to Provisional patent application #60 / 858,984 filed Nov. 14, 2006 by Phillip Campbell titled “Collapsible Hoop”. Other references are Provisional patent application #60 / 350,832 titled “Collapsible Toy Hoop”, filing date Jan. 22, 2002 by Phillip John Campbell and Non-Provisional application Ser. No. 10 / 346,469 titled “Collapsible Toy Hoop”, filing date Jan. 17, 2003 by Phillip John Campbell now abandoned.BACKGROUND[0002]1. Field of Invention[0003]The present invention relates to hoops that may be used as toys and exercise equipment for whirling about ones body.[0004]2. Description of Prior Art[0005]Historically hoops of this nature have been constructed from rigid linear hollow circular plastic tubing of a specified length. The length of tubing is formed into a circle and the two ends are mechanically fastened together to make a rigid ring or hoop that can be whirled about ones hips for entertainment or for exercise purposes. The l...
